This data release is associated with the publication "The Quasar Feedback Survey: Revealing the importance of sensitive radio imaging deeper into the radio quiet regime", published in Njeri et al. (2025), MNRAS, under review.This work presents 1.4GHz and 6 GHz radio imaging, obtained from the Very Large Array for the 29 quasars from the extended sample, to lower luminosities (QFeedS-2), of the Quasar Feedback Survey (first presented in Jarvis et al. 2021, MNRAS, 503, 1780 https://doi.org/10.1093/mnras/stab549 ). These targets are z~0.1 quasar host galaxies, selected to be luminous in [O III] emission (L[O III] &gt; 10<sup>42.1</sup><sup> </sup>erg/s). For full details of the survey description and sample selection see Njeri et al. (2025).This data release contains the L-band (1.4GHz) images produced from the Very Large Array (VLA), in A-array configuration, for each of the sources. However, although 29 sources are in the survey, 3 sources were not observed in the L-band (J0213+0042, J0232−0811 and J2304−0841). Therefore, there are 26 L-band images in this data release. The raw VLA data were obtained under proposal ID 23A-214.All normal metadata, associated with astronomical images (observation details, source details, process of imaging), is included with the fits files.We used the VLA Calibration Pipeline 2024.1.0.8 for casa version 6.6.1 to reduce our data. Imaging was performed using the casa tclean algorithm with Briggs weighting of r=0.5 for all radio maps.
